PCB drawings are also included for easy location of parts and test points. Many electrical and mechanical parts in television receivers have special safety related characteristics.

These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc.

Replacement parts which have special safety characteristics are identified in this service manual. Electrical components having such features are identified by shading in the schematics and by bold type in the parts list of this service manual.

The replacement for any safety part should be identical in value and characteristics. NOTICE: Observe all cautions and safety related notes located inside the receiver cabinet and on the receiver chassis. Operation of this receiver outside the cabinet or with the cover removed presents a shock hazard from the receiver's power supplies.

Work on the receiver should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on high voltage equipment. Do not install, remove or handle the picture tubes in any manner unless shatterproof goggles are worn. People not so equipped should be kept away while the picture tube is being handled. Keep the picture tube away from the body while handling. When service is required, observe the original lead dress.

Extra precaution should be taken to assure correct lead dress in the high voltage area. Where a short-circuit has occurred, replace those components that indicate evidence of overheating. The surface of the cathode ray tubes CRTs may generate X-Radiation, so take proper precautions when servicing.

It is recommended that a lead apron be used for shielding while handling the CRT. Use this method if possible. When replacing the CRTs, use only the designated replacement part since it is a critical component with regard to X-Radiation. High voltage must be set as prescribed under the section titled Electrical Adjustments.
